Please see About MDAnalysis: Governance for the description of how decisions are made for the MDAnalysis project.
Below is a summary of the governance model (but note that if the text on this page and the page About MDAnalysis: Governance disagree then the About MDAnalysis: Governance page takes precedence):
Project leadership is provided by a subset of contributors, the MDAnalysis Core Developers (@MDAnalysis/coredevs) who have produced substantial contributions over extended lengths of time and who remain active in reviewing issues and discussions on the various discussion channels. MDAnalysis Core Developers are granted commit rights (write access) to the GitHub source code repository. New MDAnalysis Core Developers are elected with a simple majority of current MDAnalysis Core Developers.
All decisions are made by simple majority of the MDAnalysis Core Developers.
A rotating subset of three MDAnalysis Core Developers is tasked to respond to and to investigate Code of Conduct violations.
